The Extech MN47 compact digital multimeter offers 12 functions as well as non-contact voltage detection. The built-in non-contact voltage detector quickly checks for the presence of voltage from 100 to 600 VAC. Measurements are shown on an over-sized, high-contrast LCD display and double molded housing, the MN42 also offers CAT III-600V protection.

Other features of Extech MN47 compact digital multimeters include autoranging, a 4000-count display and a basic accuracy of 0.5%. The MN47 measures AC and DC voltage to 600V and AC and DC current to 10A. Offering a resistance of 40MΩ, this Extech digital multimeter also features diode/continuity measurement. Additional measurements include capacitance (100 µF), frequency (10 MHz), temperature (1400°F) and duty cycle (0.1 to 99.9%).

The Extech MN47 compact digital multimeter ships complete with:

  • Test leads
  • Type K bead wire probe (-22 to 572°F/-30 to 300°C)
  • 9V battery
  • Carrying case
